AI Bias and Subtle Discrimination

Don't Incentivize Discrimination To Feel Better

This is an important point not just about AI software but discussions about race and gender more generally. Accurately reporting (or predicting) facts that, all too often, are the unfortunate result of a long history of oppression or simple random variation isn’t bias.

Personally, I feel that the social norm which regards accurate observation of facts such as (as mentioned in the article) racial differences in loan repayment rate conditional on wealth to be a reflection of bias is just a way of pretending society’s social warts don’t exist. Only by accurately reporting such effects can we hope to identify and rectify the causes, e.g., perhaps differences in treatment make employment less stable for certain racial groups or whether or not the bank officer looks like you affects likelihood of repayment. Our unwillingness to confront these issues places our personal interest in avoiding the risk of seeming racist/sexist over the social good of working out and addressing the causes of these differences.

Ultimately, the society I want isn’t the wink and a nod cultural in which people all mouth platitudes but we implicitly reward people for denying underrepresented groups loans or spots in colleges or whatever. I think we end up with a better society (not the best, see below) when the bank’s loan evaluation software spits out a number which bakes in all available correlations (even the racial ones) and rewards the loan officer for making good judgements of character independent of race rather than the system where the software can’t consider that factor and we reward the loan officers who evaluate the character of applications of color more negatively to compensate or the bank executives who choose not to place branches in communities of color and so on. Not only does this encourage a kind of wink and nod racism but when banks optimize profits via subtle discrimination rather than explicit consideration of the numbers one ends up creating a far higher barrier to minorities getting loans than a slight tick up in predicted default rate. If we don’t want to use features like the applicant race in decisions like loan offers, college acceptance etc.. we need to affirmatively acknowledge these correlations exist and ensure we don’t implement incentives to be subtly racist, e.g., evaluate loan officer’s performance relative to the (all factors included) default rate so we don’t implicitly reward loan officers and bank managers with biases against people of color (which itself imposes a barrier to minority loan officers).

In short, don’t let the shareholders and executives get away with passing the moral buck by saying ‘Ohh no, we don’t want to consider factors like race when offering loans’ but then turning around and using total profits as the incentive to ensure their employees do the discrimination for them. It may feel uncomfortable openly acknowledging such correlates but not only is it necessary to trace out the social causes of these ills but the other option is continued incentives for covert racism especially the use of subtle social cues of being the ‘right sort’ to identify likely success and that is what perpetuates the cycle.


A.I. ‘Bias’ Doesn’t Mean What Journalists Say it Means

In Florida, a criminal sentencing algorithm called COMPAS looks at many pieces of data about a criminal and computes the probability that they will commit new crimes. Judges use these risk scores in criminal sentencing and parole hearings to determine whether the offender should be kept in jail or released.
